Comment(by nacin):

 As said over wp-hackers by someone else: I don't think it is a good idea
 to assume that upgrades to plugins/themes are made through the WP admin
 interface.

 Take, for example, SVN. Introducing a new hook here is only going to cause
 inconsistencies. At least activation and deactivation we can largely
 control. (Deactivation less so, as the files can vanish.) Schema upgrades
 are probably best handled on a case by case basis.
